Fire stopping for Old Ford sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Fire stopping in Old Ford, done properly

A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. We work on joints between fire-resisting walls and floors, linear gaps at wall heads and small duct penetrations where the tested detail allows, and what we’re called in for most is openings left by services added after handover and penetration schedules that need working through. For commercial sealant work in Old Ford, you deal with one contact from quote to sign-off, whether it’s one building or several.

In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we’ll confirm with the quote.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Maintenance after handover

After handover, these steps help:

  • Have penetrations checked while they can still be seen
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Foam or ordinary sealant is never a fire-seal repair
  • Check risers and ceiling voids after each round of works

Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way unless the designer specifies otherwise.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

Common questions from Old Ford clients

Can work in a care setting near Old Ford go ahead while residents are there?

Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.

Do you take on work at healthcare sites like Mile End Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Which standards are fire seals tested to?

The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. An EI 60 seal kept its integrity and insulation for 60 minutes as tested; installing to the detail is what carries that across to site.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

From enquiry to sign-off

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. Planning a London job such as one in Old Ford starts with access. Give us the hours we can be on site and we will schedule to suit.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Point out any areas we must not close
  • Have the specification and drawings to hand
  • Share your working hours and any access restrictions

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

What sets the cost

What shapes the price:

  • Travel to remote or island sites
  • Site requirements such as inductions and permits
  • Whether the work must be split into stages
  • Removal of failed or old sealant

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • When you need the work done
  • Access details, including height
  • The postcode of the building
  • Any specification or named product

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, phone 01277 525 020 or send details through our quote form.

Why it’s worth doing now in Old Ford

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, and doing it once, properly, is cheaper. Getting scaffold, permits or access booked in Old Ford takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Why us?

  • Public liability insurance in place
  • Clear, fixed quotes
  • 12-month guarantee on workmanship
  • Specification-led, product-correct work

Compartment walls and floors in Old Ford

With tenants changing and fit-outs following, London buildings see service routes altered again and again. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules. Plenty of hotels sit less than 2 miles from Old Ford. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

Residences at universities like Arden University Stratford Campus (0.7 miles north-east of Old Ford) have compartment walls that must be resealed whenever services change. Shop fits in centres such as Stratford Centre, 1 mile to the north-east of Old Ford, can bring new services through fire-resisting walls between units, which then need the specified seal. On estates like Old Ford Trading Estate, which lies west of Old Ford, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
